5 Separate target-specific initialization from general
6 back-end initialization.
8 * toplev.c (init_alignments): New, split out from...
9 (process_options): ...here.
10 (backend_init_target): New, split out from...
11 (backend_init): ...here.
12 (lang_dependent_init_target): New, split out from...
13 (lang_dependent_init): ...here.
15 * toplev.h (target_reinit): Declare.
16 * expr.c (init_expr_target): Renamed from init_expr_once, since it
17 now can be called more than once. Update comments.
18 * expr.h (init_expr_target): Likewise.
19 * alias.c (init_alias_target): Renamed from init_alias_once, since it
20 now can be called more than once. Explicitly zero
21 static_reg_base_value.
22 * emit-rtl.c (init_emit_regs): New, split out from...
23 (init_emit_once): Here.
24 * regclass.c (initial_fixed_regs, initial_call_used_regs): Make
25 non-const, so that changes from command-line arguments can overwrite
26 values provided by the static initializers.
27 (initial_call_really_used_regs): New, used similarly to the above.
28 (initial_reg_names): Likewise.
29 (last_mode_for_init_move_cost): Promoted function-local static to
30 file-scope static to make it accessible outside init_move_cost.
31 (init_reg_sets): Do not initialize fixed_regs and call_used_regs yet.
32 Do not initialize inv_reg_alloc_order yet, either. Do initialize
33 reg_names since it is needed for parsing command-line options.
34 (init_move_cost): Use last_mode_for_init_move_cost instead of
35 function-local static.
36 (init_reg_sets_1): Initialize fixed_regs, call_used_regs, and
37 call_really_used_regs now. Reinitialize reg_names. Also
38 initialize inv_reg_alloc_order. Zero reg_class_subunion and
39 reg_class_superunion. Clear losing_caller_save_reg_set.
40 Preserve global registers if called more than once. Reset
41 move cost, may_move_in_cost, may_move_out_cost, and
42 last_mode_for_init_move_cost.
43 (init_reg_modes_target): Renamed from init_reg_modes_once, since it
44 can now be invoked more than once. Update comments.
45 (init_regs): Update comments.
46 (fix_register): Update initial_fixed_regs, initial_call_used_regs,
47 and initial_call_really_used_regs, instead of the non-initial
48 variables. This allows us to save the command-line register settings
49 after target reinitialization.
50 (init_reg_autoinc): Zero forbidden_inc_dec_classes.
51 * rtl.h (init_emit_regs): Declare.
52 (init_reg_modes_target, init_alias_target): Renamed as described
